贲门失驰缓症介入治疗的疗效评价

目的：评价贲门失弛缓症球囊扩张介入治疗的疗效。方法：对20例贲门失驰缓症患者行球囊扩张术。结果：20例患者共进行了31次球囊扩张，人均1．5次（其中12例扩张1次，5例扩张2次，3例扩张3次）。术后患者吞咽困难明显缓解，主要并发症为疼痛和返流。术后随访无症状期为3－13个月。结论：球囊扩张术是治疗门失弛缓症的有效方法。

WR-2721对γ线照射小鼠胃排空的防护作用

小鼠经γ线1200rad照射后胃排空受到明显抑制,如照前15min腹腔注射WR-2721 5mg或10mg对照后3天胃排空的抑制有明显改善。虽然WR-2721药物本身对胃排空具有一定的抑制作用,但经过24～48h后则可表现出对胃排空有一定程度的改善效应,这可能与该药减轻急性放射损伤的过程有关。     

A pictorial portrayal of poisoning possibilities: a public awareness approach

Areas of a high density university housing cooperative were randomly photographed following reports of decreased child supervision and increased potential for childhood poisoning and injury. A slide show was developed using these actual settings which revealed potential exposure to multiple toxic chemicals. This show was presented to the residents and demonstrated the high risk situations. Residents discovered that toxic chemicals were present in their own living environment, that many routes of exposure were possible and the high susceptibility of children during unsupervised play. As a result of this educational program, a poison prevention policy was approved with subsequent visible improvement in the community awareness and environment. This pictorial approach is a useful method for educating residents of a high density housing development about potential poisonings in their home environment and may be applied to other similar settings.     

浅析中专护生文化休克的护理策略

文化休克(culture shock),又译为文化震撼或文化震惊,是指生活在某一种文化环境中的人初次进入到另一种文化环境,如到了不同的民族、社会群体中或地区甚至国家时所产生的思想混乱与心理上精神紧张综合征。新入校中专护生,由于文化环境的改变,往往会出现孤独、焦虑、无助等文化休克的种种表现,这些现象若不能及时得到解决,将不利于他们的全面健康状态的成长与发展。众所周知,WHO明确规定,健康不但是没有疾病和身体缺陷,还要有完整的生理、心理状态和良好的社会适应能力。因此,新入校中专护生这一特殊群体所产生的文化休克现象应引起学校有…

The dental caries status and dental treatment patterns of 12-year-old children in Hong Kong

A randomly selected sample of 662 12-year-old Hong Kong children, 529 of whom were Southern Chinese and 133 non-Chinese, was clinically examined for dental caries. The DMFT values were 2.76 and 1.66 for the Chinese and non-Chinese children, respectively. The D component for the Chinese children was 2.12, while for the non-Chinese children it was only 0.45. Approximately 24.0% of the Chinese children had attended the dentist because they were in pain. Only 3.8% of the Chinese children had sought orthodontic or preventive treatment, compared with 24.0% of the non-Chinese children. Although these findings indicate the caries experience to be well below the FDI/WHO global goal for the year 2000, there is a great need to increase the level of dental awareness among Chinese children.     

γ线照后大鼠胃组织乙酰胆碱含量胆碱酯酶活性及平滑肌对乙酰胆碱反应性的变化

本文以大鼠为实验对象,观察了γ线8Gy照后胃组织内乙酰胆碱含量、胆碱酯酶活性及平滑肌对乙酰胆碱反应性的变化。结果表明,照后1/24～l天胃组织内乙酰胆碱含量明显下降,3天趋向正常,5天基本恢复至照前水平。胃组织的胆碱酯酶活性在照后l/24～5天基本无改变。在同一剂量照后1h,胃窦平滑肌对乙酰胆碱的反应与照前近似,l天后开始减弱,3天后明显下降,与正常相比有非常显著差异。

分析病区库房物资管理中存在的问题，主要有管理意识缺乏，物资领取与临床需求脱节，医疗物资分配和使用不合理，物资的保管、维护不当。应对措施：加强医疗成本管理意识；物资领取时注意计划性和灵活性相结合；库房物资使用时注意原则性和节约性相结合；库房物资规范存放，做好各类固定资产的维护、保养管理；健全病区库房管理规章制度；树立科学发展观。     

国产奎硫平合并舒必利治疗难治性精神分裂症

目的:了解舒必利合并国产奎硫平(启维)治疗难治性精神分裂症的疗效和安全性。方法:26例符合CCMD-Ⅲ精神分裂症诊断标准且临床判断属于难治性病人,予舒必利合并奎硫平治疗,疗程8周,分别在治疗前及治疗后进行阳性与阴性症状量表(PANSS)和不良反应状量表(TESS)评定。结果:合并治疗8周后总有效率65.3%。PANSS阳性、阴性及一般精神病理评分于治疗前后均有显著差异(P<0.01)。TESS总分治疗前后无显著差异(P>0.05)。副反应主要为肌张力增高、失眠、体重增加、静坐不能。结论:对于舒必利治疗反应不佳的难治性精神分裂症病人合并奎硫平治疗仍可取得较好的临床效果,安全性较高,耐受性及依从性好,可作为临床治疗难治性病人的方法之一。
